Answer: If the sum of the measures of two angles is not 90°, then they are not complementary angles.
<u>Step-by-step explanation:</u>
Contrapositive of p → q is ~q → ~p where p is the hypothesis and q is the conclusion.
Hypothesis (p) = Two angles are complementary
~p = Two angles are not complementary
Conclusion (q) = The sum of their measures is 90°
~q = The sum of their measures is not 90°
~ p → ~q = If the sum of the measures of two angles is not 90°,
then they are not complementary angles.
In triangle ABC the Value of x is B=14
Answer:
A) 151 in³ or 151 cubic inches
Step-by-step explanation:
Volume of rocket = Volume of Cylinder + Volume of Cone
Step 1
Find the volume of the cylinder
Volume of a cylinder = πr²h
r = Diameter/2
= 5/2 = 2.5 inches
h = 6 inches
Hence,
π × 2.5² × 6
= 117.81 cubic inches
Step 2
Find the volume of the cone
Volume of a cone =1/3 πr²h
h = 11 inches - 6 inches
= 5 inches
r = 2.5 inches
Hence,
1/3 × π × 2.5² × 5
= 32.72 cubic inches
Therefore:
Volume of rocket = Volume of Cylinder + Volume of Cone
= 117.81 cubic inches + 32.72 cubic inches
= 150.53 cubic inches
Approximately to the nearest inch = 151 in³ or 151 cubic inches
Option A is correct
Step-by-step explanation:
1 litre = 1000ml
780ml left
lost amount = 1000 - 780 = 220ml
